Answer 2

Answer : The correct option is, 7.58

Explanation : Given,

pOH = 6.42

pH : It is defined as the negative logarithm of the hydrogen ion concentration.

As we know that,

$pH+pOH=14$

Now put the value of pOH in this expression, we get the pH of this solution.

$pH+pOH=14$

$pH+6.42=14$

$pH=14-6.42$

$pH=7.58$

Therefore, the pH of this solution is, 7.58
